I've try this since I was little, and now I went back to play it again. For my describe of experience was the Earning, because it gives you a lot of more money, and you can also tap fast to increase of the speed and more money increase. And my last describe of my experience, was the workers and speed, because the workers and speeds gives tons of money instead of just a normal speed and a regular speed. with this a little help, you will get a lots of workers, and tons of speed. and that's it.

very fun it is a really good game. Yea it has a lot of ads. But almost every game has a lot of ads. If u just watch an ad when u level up and get the extra money it is good. Cause the game makes u watch an ad after. So u should just pick the extra money. I'm not complaining about the ads. its just it has a lot of ads. but that ain't stopping me from playing the game and having fun. AND THE BEST PART ABOUT IT IS IT IS FREE YES YOU HEARD ME ITS FREEEEEEEEEE! The workers are good. FREEEEEEE GAME!

Don't bother. Game is bugged at level 20, won't progress, and Devs never bothered to fix it. Plus, ad dependent progress gets profoundly irritating at an early stage.
